MANUFACTURE OF FUEL-BLOCKS FROM PETROLEUM.

nnmw/ SPECIFICATION firming part Of Letters Patent No. 594,739, dated November 30, 1897. 7 Application filed May 28,1897. Serial No. 638,541. (No sp fiimens.)

the following ingredients: Seventy-five toeighty-five per cent, by Weight, of refined petroleum; four to three per cent, by weight,

' of caustic soda; thirteen to eight per-cent, by

weight, of thick turpentine; five to two per cent, by Weight, of pine-resin; two and onehalf to two per cent, by Weight, of margarin, and one-half to one-fifth per cent, by Weight, of cocoanut-oil. The proportions may be varied within the limits above stated. The margarin, cocoanut-oil, and about one-third part of the caustic soda in solution of about 38 Baum are made into soap, which is well dried and divided into granules. The turpentine and pine or gallipot resin are melted together and mixed with the soap -granules. When these are well mixed, the petroleum is added and the mixture is heated to about 105 centigrade. The rest of the alkali in solution is then poured in, and the Whole is continually stirred by hand or mechanically until it attains the consistence of porridge. The mixture is kept at a temperature of 100 centigrade until it becomes quite thick, and then certained the nature of this invention and the best means I know for carrying the same into practical effect, I claim- 1. The herein described composition of matter for forming a fuel-block, consisting of petroleum, caustic soda, turpentine, pineresin, margarin and cocoanut-oil, combined substantiallyin the proportions and the manner specified.

2. The method herein described of preparing artificial fuel-blocks, consisting in first making a soap of margarin, cocoanut-oil and causticsoda, drying'and granulating the soap, then mixing therewith melted turpentine and resin, then adding petroleum, then heating and stirring the entire mixture with the further addition of caustic soda,and finally molding the mass into blocks, substantially in the manner and in the proportions specified.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, this 15th day of May, A. D. 1897.
